If you publish regularly to your website and have built up a backlog of articles, you have a valuable resource waiting to be plundered for links.
When you add a new article to your site you want it to build up some presence quickly. You probably post it to the homepage, maybe mention in on your blog (unless homepage and blog are one and the same) and it probably goes in the sidebar navigation somewhere too.
Indeed in the writing process for the article you’ve probably thought about other articles on your site and linked out to them from the new article. You then publish the article and hope that it gets listed quickly. You might even submit to Digg and Stumbleupon to get some traffic to it.
The next and crucial part is often missed though. It’s time to go through your backlog of articles on your site. They’re already indexed and getting spidered regularly (hopefully). Search through the body content of these articles for any references that could be linked to the new page, and link them up. Indeed, if it’s close enough but doesn’t quite meet your criteria, make up an extra sentence or paragraph to include your preferred keywords for the new page and link them up. Do this in a sympathetic way though, only picking the pages that are most relevant rather than adding keywords to every page of your site.
It’s not a complicated thing to do this and it shouldn’t take long in most cases but it will help with SEO and with getting your new articles the kudos they deserve.
